If the diameter of a sphere is 6 m, its hemisphere will have a volume of :

A. $$18\pi $$ m³

B. $$36\pi $$ m³

C. $$72\pi $$ m³

D. None of these

Answer: Option A

Solution(By Examveda Team)

Volume of hemisphere :
$$\eqalign{ & = \left( {\frac{2}{3}\pi \times 3 \times 3 \times 3} \right){m^3} \cr & = \left( {18\pi } \right){m^3} \cr} $$
